Abstract

Automatic threading device It is an automatic threading device used for threading for sewing machine needle and manual needle, it comprises shell, piston, press board, crochet hook, spring, button and thread gear, showing similar to a matching box or something like that it adopts the technology of mechanical focus to lead the crochet hook into the needle hole manually and exit with the help of the spring power. It solves the problem of original threading devices, for example, the trumpet threading device has trouble in threading the soft nylon thread and multiple pieces of thread, besides, the ___ threading device depends on eyesight to thread resulting in low efficiency and it does not fit for the middle-aged and old people, while the utility model possesses such advantages as follows: it can synchronize the hanging and threading processes automatically, besides, it is simple, quick, reliable and efficient to use, and it can thread multiple pieces of thread and the soft nylon thread with fluff on the surface.

Description

Automatic threading device

The utility model relates to a kind of automatic lead device that manual pin, sewing machine pin are reached the standard grade that is used for.

Existing down-lead device (claiming needle-threader again): a kind of is the down-lead device that adopts the horn mouth lead.It is directly to pass pin hole by the certain degree of hardness of line, and for soft, surperficial nylon wire villous then is difficult to pass tiny pin hole, more can not be used to wear many lines and sewing machine pin threading.Another kind be with metal wire rod make "

" the shape down-lead device, it be by people's eyesight and hand directly deformable " " shape coil tip passes pin hole, then line pierced into coil, when pulling out coil, just line is pierced in the pin hole, this down-lead device, the lead-in wire difficulty is big, not quick, is unsuitable for weak-eyed the elderly and uses.

The purpose of this utility model is to provide a kind of can wear various lines, can wear many lines, convenient to use, the widely applicable automatic lead device of making contact, going between and carrying out automatically synchronously.

The utility model is to adopt on the housing twice parallel in shape to resemble manual pin and the sewing machine pin decide pin hole, decide the vertical also crossing crochet hook manhole appendix of pin hole, one-tenth with these twice together

Shape, after 2 to 8 trumpeter worker's pins or sewing machine pin are put into and are decided pin hole, pin hole all can be on the crochet hook turnover duct, the crochet hook of lead-in wire usefulness is set on this position, duct, the piston that promotes the buckle pin with briquetting moves, make crochet hook pass pin hole and stretch out the duct, the pawl of making contact that is in both sides, exit, duct rides over line on the gib head of crochet hook simultaneously.Make piston to moving in the other direction with return spring, make the crochet hook of band line withdraw from pin hole and reach the purpose of making contact automatically and going between.

Characteristics of the present utility model: the one, this down-lead device crochet hook passes pin hole, is to adopt mechanical contraposition mode, and the reliability height is shot with unfailing accuracy, and must not lean on eyesight and hand to come contraposition, old, youngly all is suitable for, and is simple and efficient, high efficiency.The 2nd, crochet hook be opening rather than sealing, it is that it is easier than wearing to make contact, the efficient height with the mode of taking rather than with the mode of wearing that line is placed on the crochet hook.The 3rd, make contact with the U-shaped pawl of making contact, must not use hand, can a hand operated, making contact lead-in wire carries out the automaticity height synchronously automatically.

Below in conjunction with accompanying drawing embodiment is described:

Fig. 1 is this down-lead device longitudinal section.

Fig. 2 is this down-lead device right view.

With reference to Fig. 1～2, this down-lead device is made up of housing (1), piston (2), briquetting (3) crochet hook (4), spring (5), button (6), line wheel (7).The approximate match box of housing (1) profile or certain article, left part has vertical sewing machine pin locating hole (9) and manual pin locating hole (8) and crochet hook manhole appendix (10), there is horizontal piston cylinder at the wired race in middle and upper part (13), middle part, storage pin chamber groove is arranged at the bottom, right part has block slots, and there is circular hole (11,12) on the right side then face.Piston (2) is a cylinder, and an end has axle journal, and a crochet hook (4) axially is installed, the other end is the inclined-plane, and spring (5) is positioned on the left side section of housing (1) piston cylinder, and piston (2) is positioned on the right section of piston cylinder, crochet hook (4) is on spring (5) the endoporus center, and briquetting (3) is There is a circle neck body right part upper end, and the bottom is storage pin chamber (14), and left part is the U-shaped pawl (10) of making contact, right part and intersection, bottom have one "

" v notch v, right part is positioned in housing (1) block slots, and its circle neck stretches out outside the housing, and the beveled end of piston (2) drops on

In the v notch v.Storage pin chamber is in the groove of storage pin chamber, and the U-shaped pawl of making contact matches with housing (1) left surface, and the casing pipe sleeve of button (6) is contained on the briquetting circle neck, and line is taken turns (7) and is placed in the line race of housing (1).

Claims
